The prevalence of neuropsychiatric disorders and other medical illnesses was investigated in 65 nursing home residents. The authors found neuropsychiatric disorders to be present in 94% of the sample. The neuropathologic causes of these syndromes were found to be more diverse than in previous studies. The most frequent causes were degenerative, vascular, and toxic. The most common psychiatric syndromes that resulted from these neuropathologic disorders were dementia syndrome (72%), organic personality syndrome (14%), and organic psychotic disorders (12%). The most common behavioral problems, agitation and aggression, most likely reflected the high prevalence of frontal lobe damage and affected 48% of the sample. Other non-neuropsychiatric medical problems were significantly less common. While only 4% of the sample had no neuropsychiatric diagnosis, 39% had no other non-neuropsychiatric diagnosis. These results suggest that the nursing home is not used as a referral source for chronic medical conditions in general but almost exclusively for the care of chronic neuropsychiatric disorders.

Memory complaints and memory deficits were investigated in 206 consecutively admitted psychiatric inpatients at the University of Iowa Psychiatric Hospital. Forty-five percent of patients over age 60 years and 29% of patients less than 60 years old had severe memory complaints. Patients with complaints of memory loss were no more likely than patients without such complaints to have a memory deficit. In patients over age 60 years, memory complaint was more common in depression than in dementing and amnestic disorders (73% v 43%), while in younger patients memory complaint was slightly more common in dementing and amnestic disorders than in depression (57% v 41%). Increasing age was significantly correlated with increasing likelihood of memory complaint for depressed patients but not for nondepressed patients. As a result of these findings, memory complaint was found to be a statistically significant marker for depression in the elderly (sensitivity = 73%, specificity = 75%) but not in younger patients. Our results confirm the clinical observation that memory complaints are a useful marker for depressed states in the elderly.

A case is presented in which a young man with no psychiatric history and no previous exposure to psychotropic medication rapidly developed severe catatonia and autonomic hyperactivity, and an elevated creatine kinase level. He was treated with electroconvulsive therapy and recovered completely. This case suggests that a subgroup of patients who presentated with symptoms resembling those of neuroleptic malignant syndrome and who have been treated with neuroleptics may suffer from severe psychogenic catatonia.

Computed tomography of the head (HCT) was studied prospectively in 42 new geriatric psychiatry patients. Scans were obtained in 88% of the sample. Subjects underwent a complete evaluation by a geriatric psychiatrist who was blind to the HCT results. The HCT was abnormal in 32 (86%) of the 37 patients who had a scan. The most frequent finding was atrophic changes, which were discovered in ten (27%) of the 37 patients. Subcortical vascular disease was found in 14 patients (38%). Mixed pictures with both vascular disease and atrophic changes were found in nine (24%). The only statistically significant predictor of an abnormal HCT was an abnormal neurobehavioral examination. While the information gained from the HCT did not add appreciably to the clinical evaluation in determining whether there was an organic or idiopathic psychiatric syndrome, it was crucial in determining the location and nature of the central nervous system lesions.

In a study to determine the relationship between somatic symptoms and psychiatric diagnosis, 206 consecutively admitted inpatients at the University of Iowa Psychiatric hospital were given a structured medical history (MH) and physical examination (PE). Depressed patients were significantly older, had an increase in number of medical diagnoses (NDX), and were found to have a significant increase in somatic symptoms in which there was no confirmatory evidence on the PE and in which there was confirmation on the PE. When age, sex, and NDX were controlled for, depressed patients did not have an increase in either of the types of somatic symptoms noted above but did have a slight increase in the vague somatic symptoms in which PE findings would be unlikely. Our results suggest that the majority of the increases in somatic symptoms in depressed patients may not be due to depressive psychopathology but rather to their increased number of medical problems and increased age.
